JOHN L. GREVELING, OF NEW YORK, N. Y., ASSIGNOR TO THE SAFETY CAR HEATING & LIGHTING COMPANY, A CORPORATION OF NEW JERSEY.

GAS TANK AND REGULATOR.

Application filed April 1, 1908.

To all whom it may concern:

Be it known that I, JOHN L. Cnnvnnnvo, of New York, in the county of New York, State of New York, have invented certain new and useful Improvements in Gas Tanks and Regulators, of which the following is a complete specification, reference being had to the accompanying drawings.

My invention pertains to gas tanks which are usually filled with gas under consider able pressure for sake of storage, while the gas is usually utilized at a constant pressure which is lower than that within the tank.

My invention has for its particular object to provide a combined tank and pressure regulator, so constructed as to avoid the usual high pressure piping connecting the tank with the usual regulator as is common, particularly in railway car service. For this purpose I attach the regulator directly upon the tank in such a manner that communication may be readily established with the interior of the tank through as short a connection as possible, as will here in after more plainly appear.

In the drawing, Figure 1. represents a portion of a gas tank and regulator embodying one form of my invention. Fig. 11. is a partial section of a portion of the tank and regulator. Fig. III. is a partial section of a portion of a tank and a side elevaticn of one form of means establishing communication between the regulator and the tank.

Like-numerals in the various figures are used to indicate like parts.

In Figs. T. and 11., (1) represents a portion of the shell or body of the tank and (2) the head or end portion of the same, while (3) represents the body or shell portion of any suitable type of pressure regulator which may be used to regulate the flow of gas from the tank. As many types of regulators, are old in the art, description of the internal mechanism contained within the shell (3) is omitted. The regulator (3) is attached to the head (2) as by lugs 1-) and (5) and is provided with a low pressure outlet as indicated at (6) from which the gas may be led at the uniform pressure to a point of utilization. The lug 0r boss (5) (see Fig. TI.) may be provided with a projection (8) fitting more or less closely into aperture (7) in the tank head (2). This boss forms a part of the shell (3) and Specification of Letters Patent.

is provided with flanges as indicated by dotted lines (9) whereby the screws (10) may draw the said boss against the yielding gasket (12) so as to form gas tight joint between the tank head and the said boss. The port or passage (11) establishes communication between interior of tank (1) and the valve mechanism of regulator The above description applies also to Fig. Ill. save that instead of the boss (5) there is provided a valve (13) which helps to support the regulator (3), establishes communication between the regulator and tank,

and provides means whereby the regulatormay be removed without escape of gas from the tank.

In Fig. Ill. (2) is a partial section of the tank head which is provided with a screw thread (1 1) into which is screwed the valve (13) provided with a stem (15) by means of which the flow of gas from tank may be established or cut off as desired. The valve carries the flange (16) provided with a projecting boss (17) which may engage a similar female flange forming part of the regulator (3).

I do not wish in any way to limit myself to the exact design of tank or regulator or devices for establishing communication between the tank and regulator shown in the above specification and drawing, for considerable departure in the construction and details may be made without departing from the spirit of my invention which is set forth in the following claims.

I claim:

1. The combination with a closed receptacle adapted to hold a fluid under pressure; of a pressure regulator, for controlling the flow of fluid from said receptacle, comprising in its structure supporting means attached to an external portion of said receptacle; and means for operatively and directly connecting said regulator with the interior of said receptacle.

2. The combination with a tank for holding fluid under pressure; of a pressure regulator for controlling the flow of fluid from said tank having a case forming a part of said regulator; means for attaching said case in'place directly upon the tank; and means, including an extension from said case, for establishing direct operative communication between the tank and regulator.

3. The combination with a tank for holding fluid'u'nder' pressure; of a pressure regumeans for controlling the operative comlator for controlling the flow of fluid from nmnication between said regulator and tank. saldtank; cooperating means between the regulator and tank for attaching said regu- JOHN CREVELING' 5 lator directly upon said tank; means for Vitnesses:
